用硫酸铜稀溶液处理种子,是提高玉米产量的新的播前处理法。列宁格勒农业研究所C·H·德罗兹道夫于一九五一年用“列宁格勒德卡”品种的玉米进行过这种试验。下表列举了根据浸种溶液浓度不同的玉米的产量。硫酸铜溶液浸种对玉米产量的影响从表中可以看出,玉米的籽粒及青饲料的最高产量,是在浓度为160毫克硫酸铜溶于1升水中的溶液中,浸12小时的处理情况下获得的。与对照比
Treating seeds with a dilute solution of copper sulfate is a new pre-sowing method that increases corn yield. Leningrad Institute for Agricultural Research CHR Drozdov conducted this experiment in 1951 with “Leningradska” corn. The following table lists the corn production according to the concentration of soaking solution. Effect of Copper Sulphate Solution Soaking on Corn Yield As can be seen from the table, the highest yield of corn grain and green fodder was obtained in a solution with a concentration of 160 mg of copper sulfate in 1 liter of water and 12 hours of soaking of. Compared with the control
